We already talked about tensorflow and JavaFX on this blog, but tensorflow Java API is still incomplete. A mature and well documented API is DeepLearning4J . In this example we load the trained model in our application, create a canvas for writing and enter is pressed, the canvas image is resized and sent to the deeplearning4j trained model for recognition: The way it "guess" the digit is like the "hello world" for  deep neural networks. A neuron roughly mimics the human brain neuron and it has a weight, which controls when the neuron is activated. A neural network consists of many neurons linked to each other and organized in layers. What we do is provide to our neural network labeled data and adjust the weights of our neurons until it is able to correctly predict values for the given data, this is called training. Once it is trained, we test the neural network against known labeled data to measure the neural network precision (in ...
